SYA-87 Microcomputer-Based Calorimeter for Determining the Heat of Combustion of Building Materials and Products

Description

Product Introduction:

This method is applicable for determining the gross calorific value of materials and products in a constant-volume oxygen bomb calorimeter, and is used for measuring the heat of combustion of solid materials.

Product Features:

1. The building material calorimeter retains all the functions of a microcomputer system, allowing it to run general-purpose software for other tasks; at the same time, when the calorimeter’s measurement system is activated, it can automatically calibrate the water equivalent (heat capacity) of the calorimetric system and measure the heat of combustion.

2. The calorimeter for determining the calorific value of building materials employs electric stirring with blade‑type impellers in the inner cylinder and submersible electric stirring in the outer cylinder, ensuring more uniform and convenient mixing. The instrument utilizes a fuse‑type cotton‑thread ignition system.

3. Operates on the Windows operating system, with full‑Chinese prompts throughout the process and user‑friendly human–machine interaction; users can learn and start using it immediately, completing experiments simply by following the onscreen instructions.

4. It features an integrated cabinet design, eliminating the need for a separate workbench, thereby saving floor space and making inspections more convenient.
